Correct Answer: D

Rationale: Subjective distress is not universal among individuals with a mental disorder. Choice A is incorrect as not all individuals with mental illness experience distress. Choice B is incorrect because distress is just one of the criteria used in diagnosing abnormality, not the only one. Choice C is incorrect because the presence of subjective distress alone is not sufficient for a clinician to determine if someone has a mental illness.

Correct Answer: D

Rationale: The correct answer is D because in an experimental design, investigators manipulate variables to determine the effect of one on another. This process allows researchers to test causal hypotheses by manipulating one variable while keeping others constant. Choices A, B, and C are incorrect as they do not directly relate to manipulating variables in an experiment.

Correct Answer: B

Rationale: Wilhelm Wundt's approach emphasized the study of conscious experience, marking a shift towards scientific methods in psychology. Choice A, observable behavior, is associated with behaviorism and not Wundt's structuralism. Choice C, unconscious motivation, is more aligned with Freud's psychoanalytic theory. Choice D, the functions of behavior, relates more to functionalism, which was developed by William James.

Correct Answer: B

Rationale: The cognitive perspective emphasizes understanding human behavior by focusing on internal mental events such as thoughts, beliefs, and perceptions. This helps in explaining how individuals process information, solve problems, and make decisions. Choice A, the role of the unconscious, is associated with psychoanalytic theory rather than the cognitive perspective. Choice C, the interrelations among the mind, body, and behavior, is more aligned with a holistic or biopsychosocial perspective. Choice D, the adaptive value of a behavior, is more related to evolutionary psychology rather than the cognitive perspective.

Correct Answer: A

Rationale: The correct answer is A: Structuralism. Structuralism involves introspection, where individuals report their thoughts and feelings while engaging with stimuli. In this scenario, Isabel is recording her feelings and impressions while listening to music, which aligns with the introspective nature of structuralism. Choices B, C, and D are incorrect because functionalism focuses on the purpose of behaviors, behaviorism emphasizes observable behaviors and environmental influences, and humanism highlights individual growth and personal experiences rather than introspection.
